I'm attempting to make a one external reset button that will reset two Arduino Megas (master/slave setup) that are connected via I2C.

I'm using an illuminated arcade button.

It has three pins: com, normal open, normal closed.

I'm going to connect the com pin to ground and the normal open pin to the reset pin of the Master Arduino.

Will this setup reset both boards or will it only reset the Master board? Do I need to connect the reset pin of the Slave Arduino to the normal open pin on the switch? My goal is to reset BOTH board in the setup when you press the button.
